岩溶覆盖区不同土层特征不同深度其化学成分含量有一定规律性的变化。2013年1月13日在桂林理工大学雁山校区西南侧岩溶区沼泽谷地和松林坡地分别采取土样，通过提取土壤浸出液，测定其中HCO3－、NO3－、Cl －、SO2－4、Ca2＋、Mg2＋、Na＋、K＋、TN的含量，分析其基本特征及规律。在岩溶区沼泽谷地取样浅层离子总含量最高，松林坡地则在取样深度为40 cm处离子总含量较高。 SO2－4、NO3－、Ca 2＋离子含量变化有一定的规律性。取样两地土壤电导率值变化规律几乎一致，在岩溶区沼泽谷地土壤总氮含量少于松树林的总氮含量。总体阳离子和无氧化还原性的阴离子含量变化较平缓。综合各种影响因素，岩溶覆盖区土层浸出液化学成分含量变化规律存在多样性。

the coverage area of different karst soil characteristics has certain regularity of its chemical composition content of different depth change.On January 13 , 2013 in the wild goose mountain cam-pus of Guilin institute of technology university southwest karst area valley and swamp pine slope soil samples were taken respectively , in the paper,by extracting soil leachate ,determination of HCO3-、NO3-、Cl -、SO2-4 、Ca2+、Mg2+、Na +、K+、TN content, analyzes its basic characteristics and laws.In shallow valley sampling swamp total ion content in the highest ,while the pine forest sampling depth of 40cm in total ion content is higher.SO2-4 、Ca2+、NO3-ion content change has certain regularity.Sam-pling in both the soil electrical conductivity value change rule almost unanimously , in karst valley swamp soil total nitrogen content is less than the total nitrogen content of pine forest.Overall cationic and non oxidizing reducing more gentle anion content changes.Comprehensive various influence fac-tors of coverage area of karst soil leaching liquid content change rule are diverse.
